.To all whom it may co'rwein.'

`Be it, known' that I, Louis MYERS, a citizen of the United States,residingin Newark, county of Essex, and State of New-'Jersey, haveinvented certain new and useful Improvements in Safety-Chests,aof whichthe following isl a Specification.

. My present invention relates to improvements in'safety chests orreceptacles adapted to contain jewelry' or other valuables, and

rovided with an automatically operated urigla'r. alarm designed toprevent the theft of t echest or the removalof ,its contents. A

In general design the chest proper of my present invention is ofIsubstantially the same construction 'as covered by my pendingapplication filed lMarch 22nd, 1967, Serial The improvements in mypresent case relate to the 'lookin mechanism for the chest,

and to an electric alarm mechanism,` auto- .f matically controlled byfanunstable ball or weight, and `having means actuated by the lockingniechanism'for settingV and disconnecting t-he alarm mechanism so thatthe .alarm will be placed'in condition for opera'- tion when the'chestis locked, and will be chest is unlocked.

l thrown into inoperative position when t-he In order that'my inventionmay be fully understood, I will first describe the -same i withreference to the accompanying drawings, and afterward point out thenovelty 'the chestv being broken away. to exposethel ymore particularlyin the annexed claims.

` In said drawings Figure 'l is apfront elevation of my improved safetychest showing the cover raised into' open position, a part ot of the,cofvershown in Fig. 1, with the locking mechanism in shifted and'lockedposi-l tion.` Fig; 6 is a vdetail side elevationof two of the lockingbolts and their operating mechanism. Fig. 7 is a detail planjview of apartof themainbod of the chest illustrat-iner the spirit levels orleveling the chest upon its support, and also showing one of the boltreceiving so'cketsor o enings. y

The chest proper is prefera lyformed of inner and outer spaced shells 1`and 2 as fully set forth inmy above named applica tion Serial No.363,883.' Since it is'necessary to the'proper operationof my improvedautomatically controlled alarm mechanism that the .chest be placed upona perfectly level surface, I provide the spirit levels5 and 10 `in theupper edge of the walls of the main body-of the box as shown in Fig 7.

15 is the top of the box or chest which. is"

preferably Vformed of inner and outer walls or shells as described :inmy above named application. -This top may be hinged to the'main body ofthe chest or it may be entirely removable therefrom.- I have 4not shownthe details of the mounting of thek cover upon the box, but the cover ispreferably ningcd at one of its long edges'to the upper edge of the boxproper.

Lprefer to mount the locking mechanism and the alarm mechanism-entirelyupon the cover, placing these mechanisms upon the vinside of the coverso that they areentii'ely inclosed and 'protected when. the -chest islclosed and locked.

It will be observed particularlyvwith ref; ei'ence. to Fig. I that theupper edge of the' main body portion of the chest is formed with boltreceiving slots-or-.keepers 20, it being preferable to provide four ofsuch keepers 20, one near' each corner ofthe box to receive the lockinghooks 25 formed integral witli the longitudinal movable locking bolts26. There are four of these locking bolts 26, each one of which isprovided with two longitudinalslots 2'( in which engage the guiding andretaining pins 28 rigidly .mounted inthe flanged portion of the coverThese locking bolts 26 are arranged -betweeii the inner and outer wallsof ythe cover of the'chest, the` guiding pins' 28 being mounted inV saidwalls.4 The locking hooks of the bolts 26 project through slot-s 29 inthe facing flanges 30 of the cover.

35 and 36 are bolt operating levers pivotally mounted at 37 upon theyinner face of the cover 15. The opposite ends of each of theseIoperating levers 35 'and 36 are slotted or forked as indicatedin'dotted lines in Fig.-5 to engage the pins l38 upon the y lockingboltsv 26, so that whenthe levers 35 manner. i

'and 36 are moved upon their pivot 37, all

of the locking bolts 26 will be correspondinglymoved inwardly oroutwardly into 'unlocked or locke position.

For controlling and actuating the operating levers and 36,l Ihavearrangeda rock-ing arm or lever 46, centrally journaled upon theim?? face of t'he'chest4 cover at 41, and carrl vlng in its oppositeends the laterally projecting pins or lugs 42, which, engage .andoperatein the camV slots 43- formed in the operating levers 3 5 and 36,andextending at an angle to the longit-u'-, dinal axis-ot said levers.When thelever is rocked, pins 42 will cause the 'levers 35 and 36 to becorrespondingly moved forop erating the bolts.

is a permutation locksuitably mounted i in the cover ladjacentfto thefront edge and l.having-the operating-"knob or handle 51 projectingoutwaidlyin 'convenient position to be operated. This permutation lock50 is of ordinary constructiomand is not illustrated in detail in theaccompanying drawings, except to show a plurality of tumbler disks 52,each one of which is' formed with. a

notch orgate 53 in the usual 55v is a dog 'or detent pivoted at 56 `andhaving are'ctangularly projecting nose 5511 which' fis v'adapted toengage and enter thev ates 53 of all the tumblers, when the comination.of the'lock vhas been properlyset. A .leaf'spring 57 mounted upon therocking leverlO engagesthe dog Aordetent 55 and movesit intol engagementwith the gates of.

the tumble'rs when the tumblersi have been set;-. By 4this means the dogor detent 55 is engaged by the rotatablepermutation lock so that thevlever 40 can be rockedupon. its

pivot 41 for actuating'the levers 35p and 36 'toV thereby move thelocking bolts into and 'out of'locking position. j l

60' and 61 are the bells and 62 1s the hammer of an'ordin'ary electricbell. The hammer 62 isfiounted upon the spring actuated armature' lever63Avvhich is mounted in operative relation to theelectro-.magnets 64.

65 is abattery. mounted -in a compartment in one end of the body portion4ofthe chest,

' and l66 and 67 are thebattery terminals. A

-wire indicated .at 69 isrun from the battery terminal 66 to the bellterminal 68. Another wire indicated at 70 is run from the battervterminal67 to the end of'a Contact lever .71. hereinafter 4referred to,and a third wire 1n` contact 73, -the bells 6() and 61 will be sounded.

vis a hollow cylindrical box secured to the inner face of the cover 15of the saiety chest.' `This box 8O is preferably formed of 7@ someinsulating materialA such as rubber, tiber' ori-porcelain. This box8(),.is lsecured to .the facer of the chest coverl by longV screwspassing through it into .the cover as shown at 81 .and ,82. Acircular'opening -85 i575 forined in the inner wall'of the box or coverto receive a small conoidal block' 86, which-is .mountedl upon andprojects upwardly from the contact lever 71. This contact; lever 71 isfreely journaled upon a screivfST, and is engaged by leaf spring 88secured to the box '8K0 at 89, so as to tend to move the' contact endoflever 71 into engagementwith conA tact 73', and 'atthe same time elevatethe conoidalblcck "86 'in the opening 85 of lJOXSO.l 'l i 'si 90 isaspherical weight freely mounted in the cylindrical'cavityl 80? of box 86so as t0 be capable of rolling around therein'under the influence of thedisplacement (if-the Chest.v

naturally rest in the opening 85, said open- 'ing' altordmg aslightdepressionor seat for retaining 'the spherical weight in that p0-ysition. I

95 is a throw-outvlever pivoted uponpthe inner end of the bex-80 at 96and having one end* projecting through a slot 97 formed lever will berocked upon its' ivot every time the bolt is shifted longitudinally.The-i opposite end of the throw-'out lever 95 is formed witha-laterallyv projecting ,curved' blade which is presentedin the channel80b cut transversely across the end of the box 80 in position to engagethe free end 71* of the contact lever 71 to move the contact lever intoinoperative position. This throw-out lever 95 is operatedfor breakingthe circuit controllingfthe electric bell when thebolts 26 are unlocked.

*The operation of the device'will be clear from the'- Afollowing briefdescription: The 4safety 'chest is placed upon a table or other supportand arranged as nearly as practica` ble in level position. The valuablesbeing placed in the chest, the cover is closed. VV-hen vthe 'cover isVclosed, and before the 'bolts are locked, it willjbe observed that thethrow-out lever 95 is Vin positiouto engage a i a the-contact'lever 71so that the circuit tor i,

the electric bell is broken. This position or' the throivfout lever 95also holds the eonoidal block 86 withdrawn partly from the opening 85 inthe hollow block 8U. so that the ball or weight 90 will have come to aposition of rest in engagement.A with the opening 85 as shown in fulllines in Fig.

of the drawings. The lock vmechanism is then operated for locking thechest and the combination disturbed so that 'it cannot be unlockedwithout a `knowledge of the combination -As the bolts are locked it willbel observed that the throw-out lever 95 is with-y drawn'out ofengagement with the contactlever 7l so that the spring 88 will tend to-move lever-,71 into position to 'complete the circuit-which rings thebell. lVhen, -liowever, the lever 95 is withdrawn, the ball or weight 90.is in 'a position ot rest above the opening 85 so that when the springactuated contact lever 71 is released, it will m'ove .the conoidal block86 gently up into engaement with the ball or weight. 90, the

`weig t of which is sufficient to withstand the pressurev of the' spring88. In thisv position the ball or Weight 90 holds the contact lever 4outof contact with theplate 73 so that the chest may remain in this setposition untildisturbed. If the box should be'shaken or moved fromits'horizontal position, the ball or weight 90 kWill immediately rollaway from its position vof rest above the -conoidal block- 86., whichwill permit the spring 88 to force the ylever 71 into contact position,lwhich will cause the electric bell to ring. The moment this action hastaken' place, the conoidal rblock 86 will have assumed a positionprojecting up through the opening l into the box 80, sotliatthe ballorweiglit 90 cannot by any possible means be replaced in -position tobreak'tlie circuitand stop the alarm. The bell will, therefore,.continue to ring, and will attract attention to the unauthorizeddisturbance of the chest, until the chest is unlocked by the personhaving knowledge of the combination. Then the chest is unlocked, theelectric circuit is broken as above explained,'and the alarm arrested.

It will -be observed from Fig. 2 of the drawings that the sound from theelectrical alarm has free outlet through the openings in the inner wallof the cover 15 and through opening lOl. in the outer wall of the coverinto the perforatedl raised crown` pli'ece 102secured to the top of .thecover.
